At 375-450 lbs, nutrition changes carry medical implications that lighter frames don’t face. Before adjusting protein intake, get clearance from your physician. This guide assumes medical approval.
Your target: 1,600-2,000 calories daily with doctor-set protein daily. That’s approximately 110-150g, adjusted for lean mass and medical guidance.
Why Protein Comes First
On a deficit, your body looks for fuel. Without adequate protein, it burns muscle tissue. You end up lighter but weaker, with a metabolism that slows down and makes future fat loss harder.
Protein prevents that. It preserves lean mass, keeps your metabolic rate higher, and controls hunger better than any other macronutrient. At 1,600-2,000 calories daily, that matters.
Meal Structure
Keep it simple. Complex recipes fail when energy is low or mobility is limited.
- Breakfast: 25-35g protein (eggs, Greek yogurt, shake)
- Lunch: 35-45g protein (rotisserie chicken, deli meat, canned fish)
- Snack: 20-25g protein (shake, cheese, yogurt)
- Dinner: 30-40g protein (baked fish, chicken, lean beef)
- Evening (if needed): 15-25g protein (casein shake)
Pre-cooked proteins are your best option. Rotisserie chicken, pre-cooked eggs, canned tuna, deli meat. Remove every barrier between you and hitting your target.
Best Protein Sources
- Fatty fish (salmon, mackerel): omega-3s reduce joint inflammation
- Eggs: complete protein, minimal prep
- Greek yogurt: protein plus probiotics
- Chicken thighs: collagen-rich connective tissue supports your joints
- Whey protein: lowest-friction delivery when cooking is difficult
- Bone broth: direct collagen for joint tissue
Limit processed meats and fried proteins. They add inflammation without adding value.
Training Note
At this weight, movement is for health, not calorie burning. Your fat loss comes from nutrition.
Start where you are. Standing is movement. Walking to the mailbox is movement. Water-based exercise if you have pool access. Seated movements if standing is difficult.
Any movement counts. Every step forward is progress. There is no movement too small.
Medical Note
At this weight, nutritional changes affect medications, blood pressure, blood sugar, and organ function. Your doctor must clear you before you begin.
Get kidney function tested before increasing protein. Check blood pressure, fasting glucose, and A1C to establish your baseline. If your doctor sets a protein limit different from this guide, follow their number. It overrides everything else.
This guide is educational, not medical advice. Your medical team is your starting line.
Bottom Line
Hit your protein target daily. 1,600-2,000 calories daily. Train consistently. The rest is patience and adherence.
There are no hacks. No secrets. Just consistent execution of the basics until the basics produce results. They always do, given enough time.
